I can't comment on the price or condition, but I can comment on the car since I own one that is a Jan 2011 build. It has more options as shown below and the MSRP was $73,000. The 19" LS2 tires that come with the iX sport package are a potential problem as you can see from the "Consolidated RFT Failures/Issues Thread" in this forum. A lot of us have changed the tires to a different size and have not experienced any more problems. At $400 or so per tire, you have to figure the cost into the price you pay.

The tire problems seemed to occur more in the 2010-2011 and early 2012 time periods than after that time. This may be because the tires were improved after that or the roads were improved (they were really bad in the winter of 2010-11) or perhaps some changes in the dynamic suspension were incorporated. You didn't list the dynamic suspension so that's not a concern.

The tip in problem was not severe with my car and seems to have been solved with the latest software update. Whether you can get BMW to update your software is another question that is addressed in this thread. The update seems to have worked for me so far, but I don't have enough mileage since the update to be sure. If you like the throttle response of the car that you are looking at, then you don't have a problem.

The steering problem was never there on the X-drive cars which in 2011 incorporated hydraulic steering instead of the then problematic electric steering on the RWD cars. The 2013 X-drive models incorporate electric steering, but I prefer the hydraulic version. I don't know which version the 2012 models have.

Other than the tires, the car has been good to me after 18,000 miles and two years. If the price and condition are right for you, I would go for it.
